what is the value of x

Answers

Answer: 7

Step-by-step explanation: First distribute the subtraction sign (negative one) to x and -3. Now we have 12 -1x + 3 = 8. Now combine 12 and 3 then subtract 15 from both sides to get -1x = -7. Now divide both sides by -1 to get x = 7.

Hope this helps!

Answer:

Step-by-step explanation:

12-(x-3) =8

12 -x +3 = 8

15 - x = 8

- 15.    -15

Azucena vende un automóvil en $37,500.00, sin embargo se devalúa el 18% por cuestiones de uso y degradación de los materiales. Determine el precio final de venta.

Answers

Answer:

$30,750

Step-by-step explanation:.

Paso uno:

datos dados

costo del auto = $ 37,500

% degradación = 18%

= 18/100 * 37,500

= 0,18 * 37,500

= $ 6750

Segundo paso:

deje que el costo total sea T

Por lo tanto

T = coste del coche-% de degradación

T = 37.500-6750

T = 30,750

Next you have to know the rules regarding negatives and positive... if you know that, you should be able to work out that it would be (x-4)(x+4)... you can check this using the foil method (x times x, x times 4, -4 times x and -4 times 4) or smiley face method... hope this helpedFactorised means put into brackets...
